Acts or omissions of a third party which has a contractual relationship with the responsible party could not be offered as a defence under the OPA unless the responsible party was able to show that it had exercised due care and taken precautions against foreseeable acts or omissions.
Los actos u omisiones de un tercero ligado por una relación contractual con la parte responsable no podrán invocarse como excepciones con arreglo a la Ley de 1990 a menos que la parte responsable pueda demostrar que obró con la debida diligencia y tomó precauciones contra actos u omisiones previsibles.
